6 DEVICE OPERATION
FIRST-TIME USE
6.1
An important step during the first-time use of the device is to initialize the GPS
receiver with the visible satellites of your area.
Locate an open space with
top label looking up) in a stand-still position for about a minute.
This ensures that the GPS receiver will quickly discover available satellites. GPS
sequence first displays (stratum 0) date & time data. After that, it needs to fix position
(latitude and longitude coordinates) via 4 satellites (at minimum).
It can take anywhere from 30 seconds to 3 minutes for the GPS receiver to gather
enough satellite data to get a position fix for the first
first usage (GPS cold start). After that, GPS will be fully operational in same
location after 5-6 seconds. (warm start under open sky).
If some or all the data is
updated information from the satellites before it can accurately fix a current position.
The types of data that are out-of-date or missing determine how long the GPS
receiver takes to initialize. If the Uranus is several hundred miles away from where
it was last used, or has been stored for a prolonged period of time, initialization will
take longer.
[Please note that internal battery replacement will require a GPS cold start initialization process]
Uranus battery is fully charged, straight out of the factory. However, we recommend
plugging the USB cable and re-charge the battery. (if the device is left for a long
time on the shelf the battery levels will be lower than expected) A full charge time
may take 2.5 hours when the battery is at very low power levels.
